My Quail question

So I have currently 9 Coturnix quail (that I hatched) and at 3 weeks I could tell I had 3 males 6 females, than yesterday while cleaning the coop I noticed 4 males and 5 females..... This is fine but I just wonder if anyone else has encountered this?

The birds are 6 weeks old this Thursday and I just noticed the 4th male last night... does it actually take 6 weeks for the colors to truly show through?

No you just missed the other one before. The colors that do autosex can usually be sexed visually by three weeks. This only applies to pharaoh or golden colored coturnix, all other coturnix must be vent sexed. I'm not sure what colors you have but when posting try to tell us what type of birds they are so we can answer more clearly.
